Mountain Lion: Messages/Screen Sharing

I am currently using OS Lion IChat as it allows me to do screensharing to help my technically-challenged mother.  I understand that in Mountain Lion iChat has gone away, absorbed into Messages.  Does Messages/iChat, whatever the new flavor, still support screensharing?  I want to know this before upgrading to Mountain Lion.  If not I am likely to stick with Lion.

HI,
Messages is basically iChat+ and will do everything that iChat does PLUS the iMessages bit to iOS devices (And other people using Apple IDs in Messages)
Menus such as the Video menu (for Screen Sharing) look very similar
It is fair to say that not everything is in the same place but it is not hard to adjust.

  • Messages Screen Sharing Ends with a "Hanging" Desktop Screen

    Since the OS X 10.8.1 update, Messages screen sharing – that used to work well in my environment – everytime ends up with a hanging desktop screen. That means: The screen of the desktop, where Messages screen sharing took place, freezes. I have to swipe to another desktop in order to successfully quit Messages via the dock context menu. After that, its desktop screen is responsive again.
    This happens independant of who ends the screen sharing session.
    It used to work seemlessly before OS X 10.8.1. So I think there is an issue with this update, Messages and the screens (desktops) management.

    Hi,
    As Screen Sharing does tend to involve a change from the Shared Screen at one resolution changing to your screen at possibly another (which for some produces the White Screen In Sharing) I thought it might pay to look at the method when wanting to go back to your own screen during a Screen Sharing Chat
    I would still report it here
    http://www.apple.com/feedback/ichat.html
    Obviously you have to use some of the free text area to state your OS version and Messages version at it will not appears in any of the drop downs.

  • How do I switch remote desktops with lion server screen sharing?

    When I sometimes use the Lion Server screen sharing feature to take over my iMac using my Macbook, I find that I'm not able to switch desktops on the remote computer, i.e. using the three finger swipe.
    Both are running the latest versions of Lion Server.
    Now there MUST be some way to do that right?
    Who knows?

    Hi John, perhaps I did not express myself clearly.
    My desktop iMac is set up with multiple desktops (desktop 1 for system stuff, desktop 2 for mail, messages, skype etc, desktop 3 for Safari and desktop 4 for text proessing, VM-Ware and other work).
    When I work on that machine I'm logged in as one user and use the three finger swipe left and right or the Cmd-1 thru Cmd-4 keys to switch between those desktops.
    I haven't founf how to do that from my a remotely connected MacBook Pro.
    Both of which are running Mountain Lion in the mean time. The iMac runs Mountain Lion Server and the MBP has ML Server installed as well, but nut implemented. Just to be able to use the remote screen...
    Hope this makes my question a bit mre clear...

  • Mountain Lion Messages won't connect / go online

    For the last few days Mountain Lion Messages won't connect / go online. Prior to that it would disconnec at random and it would be difficult to make it connect again. But now it's totally refusing to go online.

    I solved the problem, with the help of a friend!
    Turns out, even though Messages in Mountain Lion won't prompt you about this in any way, there is a difference between your @mac.com email and your @me.com email.
    Messages on Mountain Lion has an iChat built in, but is actually at the same time a new protocol which does not use AIM like iChat. So, it's both AIM iChat and something new.
    As soon as I added a new account inside Messages on Mountain Lion with @me.com I could reconnect and all is fine.
    Apple, this is a lot less obvious to the end user than you might think. You have switched online services a few time and it always gets better and better. But Messages in Mountain Lion should prompt the user to add the @me.com address if this is required to use the software!

  • Odd behavior during full screen video chat with Mountain Lion Messages?

    I've recently upgraded to Mountain Lion on two MacBook Pros (from Lion) and have started to use the new Messages app. I've been using iChat for years and found it reliable for the most part.
    However, I've noticed a new behavior that seems like a bug in the new Messages app.
    Steps to reproduce:
    1. Open Messages app
    2. Initiate a non-FaceTime video chat via the Buddy List or the main Messages window video button
    3. Once the video is started, click on the Full Screen button in the window title bar or in the black toolbar at the bottom of the video
    4. After the video has gone full screen, move the mouse cursor
    5. At this point, the video will slide over (like a Mission Control / Exposé space). The video chat is actually STILL running in full screen view as a dedicated space -- you can slide back with the trackpad or the keyboard as per normal Mission Control controls.
    Step 5 is NOT the correct behavior as per OS X 10.7 Lion. Not to mention, the black toolbar is unusable and it's hard to reach the menu bar Full Screen toggle button since moving the cursor even one pixel makes the screen slide over.
    Has anyone experienced this? If yes, is there a solution? How do we bring this to Apple's attention for a future fix?

    I got the machine to reboot but I had to hold down the power button. I found an article on macworld that said to use the command +control+eject buttons to restart but no go. Nothing.
    There really... REALLY ought to be some way to exit full screen in such a case.

  • Lion Server Screen Sharing for Adminstrator

    I'm having difficulty using my Administrator account for remote screen sharing after the upgrade to Lion Server.  All other remote access tools work (Server Admin, SSH, file sharing, etc.).  I'm also using LogMeIn to get to the server and, if I make an adjustment to standard user account to allow for server administration that account can use screen sharing with no problems.  Only my administrator account does not seem to work.  Has anyone else seen this?

  • Messages Screen Sharing

    Messages won't allow me to share my screen or to request to share someone else's. I'm tyring to do it with my wife's computer running 10.8 on a separate network and the option is greyed out in the dropdown. I've ensured that Screen Sharing is enabled within messages and in the system preferences "sharing" pane.
    We are both running 10.8 and using iMessage. We were both able to before the upgrade.
    Any suggestions?
    Thanks for your help.

    Hi,
    That one is so good it's wrong   needs modifying.
    You do not have to have System Preferences > Screen Sharing Enable at all.
    That is for a totally different app that is in the OS  and can be activated from the Finder.
    In the Finder > Go Menu > Go to Server
    Type in VNC:// and then IP of a LAN based computer  (Such as any Bonjour computer)
    This will then Invoke the Screen Sharing App and link your with a VNC connection and show your their Desktop (if they accept).
    You can do it to a Public IP (The modem of a contact) but they need to Forward the Port the VNC connection is On to their Computer.
    This Process does use the Apple Remote Desktop engine the same as iChat/Messages does.
    However iChat/Messages  makes the connection using SIP (Session Initiation Protocol) which deals with the routing through the Modem and any router at the other end an adds a VNC connection Along side and Audio Only chat.
    It should read like this:-
    Additions in italics.  Strike throughs for not needs action/text
    • Go to your Apple Logo / System Preference / Sharing
    • On the mac(s) that you would like to screen share , Turn on Screen Sharing. Allow Access / All Users  Not needed
    • Open iMessage app on your mac
    • iChat Style Buddy Lists are not displayed in iMessage by default. You will notice that there is no Screen Sharing button on iMessage as it was on iChat.   There is (a Button) on the Buddy lists.
    • To activate it, go to the ‘Messages’ menu at the top menu bar and select Accounts and turn on ‘ Bonjour ‘
    In fact Enable any Jabber or AIM valid Account  It does not have to be just Bonjour
    • Once you turn on Bonjour Any Enabled Account you will notice the Bonjour name shows up at the bottom left hand corner of the iMessage window.
    • Now under the Window tab, click on "Buddies" or COMMAND + 1 ( number 1 )
    • You will now see the an iChat Style Buddy list pop up but any Bonjour only list may be empty.
    This List is a combined list at present.
    Go to Mesages Menu > Preferences > General Section and untick the line about "gathering all accounts"
    • If you have not added an AIM or Jabber based Account do this:-
    Messages menu again and under Preferences, go into ACCOUNTs and click on the + at the bottom corner and add an AIM or Jabber account .
    Note : you will need an AIM/Jabber/Google account ( just like you did on iChat before )
    • Once you log in successfully, You’ll notice your list appears and you’ll see the familiar Screen Share button located at the bottom centre of the Buddy List window.
    Now go to the Video Menu and Enable Screen Sharing at your end.
    Text you Buddy that is using AIM Screen Names or a Jabber/Google/Facebook ID on iChat or Messages and get them to enable Screen Sharing as well.
    To activate, simply click on it and it will send them a request.
    Alternatively Highlight the Buddy and use the Buddies Menu
    Alternatively to that Right click the Buddy and use the Contextual Menu.
    NOTE:-
    Screen Sharing like Audio Only chats and Video Chats is AIM to AIM (including Valid Apple ID options) or Jabber to Jabber (which includes GoogleTalk and Facebook IDs) using iChat or Messages on both computers.

  • OSX Mountain Lion "Messages" will not let me sign in...

    I cannot for the life of me get messages to work on the new OSX mountain lion.  I keep getting this alert when trying to sign in:
    "COULD NOT SIGN INTO iMESSAGE. The server encountered an error processing registration.  Please try again later."
    Any ideas?  I have restarted both my macbook and macpro, reset my apple ID password... no love.

    I have spent over 40 hour walking through this issue with Apple senior tier engineering support with Apple for Mountain Lion and Developer support, plus the Apple store genius bar and their high level connection, Getting no where trying to resolve same issue it seems.  The only thing I can get to work is AIM to video chat or share screens.  Messages accounts have added 5 other account .mac accounts and I can not sign into any of them or remove any of them either.  Over time I have had a .mac address that was made into a mobile me address that was then converted into a .mac email again and became a cloud account. And I have a developer account that has a separate name that works with iTunes connect.  When I try to manage accounts to change the password of one it corrupts the the password of the other. When I try the change emails of one it says it is in use by the other.
    There are 2 accounts for the iTunes and App Store. 
    Messages is choking on my 2 accounts and there is a definite unresolved problem with the cloud in regard to them it seems.

  • Mountain lion messages problem

    Hi
    I have just set up my new imac, but I'm having problems with Messages.
    I've set up my account, but can't seem to connect to people I was in regular contact with in ichat on the old system.
    My status shows as online in the application menu (Messages > My status), but offline in the menubar
    There also seems to be no way of making custom status items - or have I missed something?
    Tamasin

    HI,
    You missed something (at least from the  way I am reading your post).
    Messages is capable of doing everything that iChat could/can do  and also has the iMesages ability.
    An iMessages account does not replace any of the other Accounts (IM Screen Names and IDs) you were using before.
    iMessages needs an Apple ID.
    This can be separate from your Apple Support Communities Login and your iTunes Account or even any iCloud Account you might be using separately.
    If in iChat you had an AIM Login with an AIM or Apple issued (AIM Valid ID) or a Jabber (includes Google ID) then these need to be added to Messages.
    This is done in the normal way (The + icon at the bottom of the list in Messages > Preferences > Accounts)
    Or you can enable them in System Preferences > Mail, Contacts and Calendars (for the Messages app)
    The Menu Bar icon refers to Buddy lists (non iMessages Accounts or iChat Accounts if you like) in terms of Status.
    The Messages Menu > Status should apply to the Same Buddy List(s) as opposed to the iMessages account.
    It sounds like you have only set up an iMessages account.

  • New Mac -Mountain Lion - Messages- Empty buddy list

    Hi Everyone,
    Got a new Macbook air that I updated straigt to Mountain Lion before opening any software.
    Everything is syncked happily under the Icloud, but with "Messages" replacing Ichat, I endup with an empty Buddy list.
    Any reason why AIM and .Mac buddys are not imported ?
    Thanks
    Sophia

    Hi,
    IN the Window menu do you have an item for "Buddies" with the CMD + 1 keystrokes listed ?
    IF so go to Messages > Preferences > General section and untick the item that Gathers the "Accounts" to one list.
    Now from the Window Menu you should have individual CMD + # keystrokes listed fro as many Account (Screen Names and IDs) as are logged in.
    Can you see them ?

  • After Lion install screen sharing won't accept my password

    I just updated my *headless* mac-mini to 10.7.  As soon as it rebooted
    Since updating to OS 10.7 on my Mac Mini, I have been unable to log in via Screen Sharing (using my 10.7 installed Mac Pro).  I continually receive the error "Authenticaion failed to 'MacMini'. Please verify you have entered the correct name and password."  The name and password are correct, and the mac-mini lets me "Connect As ..." with the username and password.  Only the Screen Sharing application fails to authenticate.  I had no troubles  an hour ago when it had Snow Leopard installed.
    Any solution before I have to travel to this mini?
    Thanks,
    Jim

    My family has multiple Macs at home and I also help a friend at a remote location.  What is weird, is I was able to do screen sharing with the Mac at the remote location and a couple at home, but was not able to get screen sharing to work on the majority of our Macs at home.  Rebooting did not help.  Deleting my user login and corresponding home folder (then rebooting) and recreating a new user under the same login name that was deleted did not help.  Repairing permissions in Disk Utility did not help.  I did not try creating a user under a totally different login name and setting up screen sharing to share with that user name.  I was going to try that this morning.  However, on another thread, someone offered another thing to try.  I tried it and it worked.
    This is what eventually worked for me...  This work around seems to expose that there is definitely a bug:
    https://discussions.apple.com/message/15812668#15812668
    Quote from andifor:
    "Full name and account name on my computers are also the same.
    But I did some deviation last time I tried. I changed my name on the connection dialog. I changed the name from "user" to "uSer" (changed one letter to capital) and it did work!
    So if you login name is "peter", change it to "pEter" or "peTer", just on the login screen.
    Looks more and more like a bug and only Apple can help. Does anybody know, if they are monitoring these discussions or is there a possibility to log some bug report?"
